DEVICE FOR REGULATING THE QUALITY OF GAS.

Specification of Letters Patent.

Patented Dec. 18, 1906.

Application led March 7,1906- Serial No. 304.713.

T n/ZZ whom, Zit may concern:

Be it known that I, CHARLES MATTHEWS, J r., a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Devices for Regulating the Quality of Gas, of which the following is a specification, reference being had to the accomp anying drawings.

It is well known that in the production of illuminating-gas from gasolene the variations in the weight of the gas are very considerable, due to the extent to which air is saturated It is necessary at times to mix a proper amount of air with the gas already formed in order to produce a satisfactory article for illuminating purposes, and according to the amount of air admitted with the gas the weight of the gas varies. Taking advantage of this principle, regulating devices or mixers have been produced comprising a movable body in a closed chamber, which body is so supported as to be easily aected by variations in the weight of the gas and which will when moved actuate suitable valve mechanism that controls the admission of air to the chamber, and thereby tend to admit to the chamber the required amount of air to mix with the rich or heavilysaturated vapor or gas.

My invention relates to devices of the general character above outlined, and has for its object to produce a delicately responsive and more simply constructed device than those heretofore employed and which will at all times act to produce a proper mixture for perfect illumination. I attain this object as illustrated in the drawings and hereinafter specifically described.

That which I believe to be new is set forth in the claims.

In the drawings, Figure 1 is a vertical section through thevessel in which gas is received from a carbureter and to which air is adapted to be supplied in suitable quantities and showing also my improved means in such vessel for regulating the admission of gas and air thereto. Fig. 2 is an enlarged detail of a portion of the valve mechanism, and Fig. 3 is a horizontal section at line 3 3 of Fig. 1.

Referring to the several figures of the drawings, in which corresponding parts are indicated by the same reference-numerals, 5 indicates a hollow vessel of any suitable size and shape and adapted to receive gas from a carbureter or other source of supply, as well as air to be mixed with thegas. In the construction shown the supply of gas is received through a pipe 6, and the air to be mixed therewith is received through a suitable pipe 7. As shown, the pipe 7 is located directly beneath the pipe 6, the discharge-openings in said pipes facing each other.

8 and 9 indicate valves adapted, respectively, to close the discharge-openings in the pipes 6 7. These valves 8 9 have a common valve-stem 10.

11 indicates a yoke fixedly secured to the valve-stem intermediate of the valves 8 9, which yoke, as shown, surrounds the end of the pipe 6, that projects into the vessel 5, to the end of which yoke is attached an operating-rod 12.

13 indicates an air-tight float, preferably of thin sheet metal and in the form of a ball or globe. This oat moves upon an axis or center intersecting itself, and to this end has secured to it a pivot-pin 14, which passes through the float considerably at one side of the center thereof and has the lowerportion of its projecting ends formed to present a comparatively sharp edge, which projecting ends rest upon suitable supporting-brackets 15, secured to opposite sides of the vessel v'5. It is evident, of course, that instead of providing a rod, such as 14, that extends entirely through the float, two short pivot-pins might be brazed or otherwise attached to the face of the float.

16 indicates a weight carried by the float between the pivot-rod 14 and the adjacent wall of the float. This weight 16 is suHicient to hold the float and the valve mechanism attached thereto at the opposite side evenly balanced on its pivot V14.

17 indicates a short arm projecting out from the float over the ends of the pipes 6 7, to which arm the rod 12 is suitably attached, the attachment being in the construction shown through the medium of a link 18.

19 indicates a pipe communicating with the interior ofthe vessel 5, through which the illuminating mixture passes off for consumption.

20 indicates a base for the vessel 5 to raise the bottom of the vessel sufficiently to permit the entrance of the air-pipe 7 through the bottom of the vessel, as shown.

W'ith the parts arranged as shown gas under pressure will pass into the vessel through the pipe 6, and if richer than de- IOO IIO

sirable for illuminating purposes its density will cause a slight turning of the float 13 on its pivot, which slight turning will nedessarily cause an upward lift on the valve-stem l0, such movement of the valve-stem raising the valve 8 toward `or against its seat in the pipe 6 and raising the valve 9 off of its seat in the pipe 7. This movement of the two valves simultaneously checks the inflow of the heavy vapor through the pipe 6 and allows of an inflow of air through the pipe 7, such inflow of air continuing until the proper mixture of gas and air has been had to provide a proper illuminant for passing off through the pipe 19. From time to time the valves 8 and 9 will be thus automatically moved so as to insure at all times the proper mixture in the vessel. By providing' the fioat with a pivot a considerable distance from the center and weighting that side of the float adjacent to the pivot I provide a device that is very susceptible to the variations in the weight of the gas, and am thereby enabled to regulate to a very fine degree the mixture of the air and gas in the required propor-v tions.

That which I claim as my invention, and desire to secure by Letters Patent, is-

1. In a mixing device of the class described, the combination with a gas-holding vessel, of pipes for admitting gas and air thereto, a valve for each pipe, a float pivotally secured in said vessel and moving upon an axis intersecting itself, and means carried by said float for operating both of said valves simultaneously, substantially as specified.

2. In a mixing device of the class described, the combination with a gas-holding vessel, of pipes for admitting gas and air thereto, the ends of the pipes projecting into the vessel and having their discharge openings opposite to each other, two valves connected together and each adapted to close one of said pipe-openings, a movable float in said vessel and moving upon an axis intersecting itself, and a connection between said iioat and said connected valves, substantially as specified.

3. In a mixing device of the class described, the combination with a gas-holding vessel, of pipes for admitting gas and air thereto, the ends of the pipes projecting into the vessel and having their discharge-openings opposite to each other, two valves connected together and each adapted to close one of said pipe-openings, a movable float in said vessel and moving upon an axis intersecting itself, a yoke connected with thevalves and surrounding one of said pipes, and a connection between said yoke and float, substantially as specified.

4. In a mixing device of the class described, the combination with a gas-holding vessel, of a float, a pivot therefor located between the center of the float and one side thereof, said lioat being weighted on the side nearest said pivot, pipes for admitting gas and air to the vessel, and means connected to the iioat opposite its weighted side for moving said valves simultaneously, substantially as specified.

5. In a mixing device of the class described, the combination with a gas-holding vessel, of a fioat heavier at one side than at the other, a pivot adjacent to the said heavier side of the float, a valve, and means for connecting said valve and float, substantially as specified.
